Product detailed description

IVAR.TER-SELT DN 50 consists of a two-way ball valve SELTRON BVQ with internal thread Rp 2" and the AQD actuator mounted. The assembly is used for on/off zone control and as a shut-off element in heating, ventilation and air conditioning (HVAC), in cooling and in hot water distribution; it is also suitable for use in industry and agriculture.

AQD Actuator

• supply voltage 230 V~, two-point ON/OFF control
• torque 8 Nm, rotation by 90° in 13 s
• power consumption 5 W, less than 0.25 W in standby mode
• manual mode button disconnects the motor and the valve is adjusted using a rotating controller; the current position is indicated on the actuator
• the opening direction is changed by a switch hidden under the rotating controller
• the actuator is mounted on the valve by pressing with one hand without tools, a locking mechanism prevents unintentional release
• protection class IP42, protection class II according to EN 60730-1, cable length 1 m, housing made of PC thermoplastic

Valve BVQ DN 50

• connection by internal thread Rp 2", construction length 124.3 mm

Frequently asked questions

What is the two-way zone valve BVQ DN 50 with AQD actuator used for?
For on/off zone control and as a shut-off element in heating, cooling, air conditioning and hot water preparation. It is also suitable for use in industrial and agricultural distribution systems.

Can the valve be adjusted manually?
Yes. Pressing the manual mode button disconnects the motor and the valve is adjusted using a rotating controller; pressing the button again cancels the manual mode.

Is any tool required to mount the actuator on the valve?
No, the actuator is mounted on the valve body by pressing with one hand and secured by a locking mechanism. It can be easily removed during disassembly.

At what fluid temperature can the valve operate?
The working fluid temperature can be between 10 and 90 °C. The actuator can withstand ambient temperatures of 0 to +55 °C at a humidity of up to 85 % without condensation.
